If R is installed, I would recommend reinstalling GRASS, during installation it tries to automatically look for it, so there is a chance it will work then. I would recommend subscribing to grass-user mailing list and ask more questions there.<br></div><div><br></div><div>Anna</div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div></div><div>Best regards </div><font color="#888888"><div><br></div><div>Tom</div></font></div>
